The TV chef, who was booted out of the jungle on Saturday, said the loved-up pair would sneak away from camp to talk out of sight of the cameras, reports the Daily Star.

John, 50, said: “There were times when the pair disappeared off together. I have to say that. There are things the viewers wouldn’t have seen or heard in there. Relationships are formed. And if you want to talk privately you put your hand over your mic.”

He added: “There are periods when you can disappear for private conversations. I did it. I’m not sure if I got away with it. But I confided in Katie more than I probably should have done.”

But the camp cook said he wished the pair well, adding: “I liked both of them. Marc tried to make everyone feel comfortable in camp. Everyone had moments of doubt and homesickness. He was really charming. And Cerys is a one-off. She is very special and generous. She is just beautiful.”
